Millie, who stars in Made In Chelsea, is unlikely to have been introduced to the chart topping stars before as they aren't regulars on the wealthy west London scene.

Still, the 22-year-old was all smiles as she stood on the red carpet with her arms wrapped around her man.

He tweeted excitedly from the red carpet about seeing some of his friends from the world of music and said: 'Mad turn out… Everyone is 'ere!'#

Stephen, 28, posted a picture of the remaining snack and said: 'Film hasn't even started and look what the bird has done to the popcorn! Liberties.'

He said: 'In my home town in East London, the centre of the 2012 Olympics, it has always been very deprived compared to the rest of the city. Where there is deprivation there is poverty, where there is poverty there is crime.'

'The children brought up in areas such as this face an uphill struggle to succeed in life.'

'Now I feel that when you are only a kid growing up in these environments where they are getting beaten by their parents and they are made to feel like they have done something wrong, they are getting abused whether its mental or physical or sexual abuse, the way they act as an adult is a product of that'

All the young characters are fighting for respect and their lives inter-loop through violence. Plan B narrates poetry throughout providing a running commentary which complement the shocking images on screen.
